Dear List,
One of our client who wants to replace his old SIngle Loop Controller based system (in a Chemical Recovery Plant) to a newer PLC based system. The new system installed is SIEMENS SIMATIC S7.
The old controllers were Fischer & Porter Micro DCI. I have a list of their parameters. However, there is no conversion factors that could
translate them into the SIMATIC S7 PID block (FB41, Continous Control). If anyone has done a similar job or know the conversion parameters, then it would be a great help to easily convert the loops instead of re-tuning all of them.
Also, in the same plant, there is a boiler that burns black liqour (coming from the fibre mill after it is used to cook pulp). This boiler
has a Drum Level cascade loop, which has no available information. Any information about this would be welcome.
Thanks in advance,
Shahid
